Yes, that was mainly done to improve performance. Several testers reported significant speed improvements after applying that change. It makes sense, because if a surface was in VRAM, Lock() has to transfer it all into system RAM before it can give you a pointer to it, and Unlock() has to push it back to VRAM... and in some places the geniuses at WW draw stuff pixel by pixel, causing repeated lock/unlock cycles.
Why are you working with PNG? I'm pretty sure that a simple read/write loop into a 16 bit BMP will work faster than read/process/write into a PNG, doing image compression here feels like a waste of time to me.
